Serine proteases, such as trypsin and chymotrypsin, are the primary digestive enzymes in lepidopteran larvae, and are also involved in Bacillus thuringiensis (Bt) protoxin activation and protoxin/toxin degradation. We ...
Characterization of Phlebotomus papatasi peritrophins, and the role of PpPer1 in Leishmania major survival in its natural vector

Coutinho-Abreu, Iliano V.; Sharma, Narinder K.; Robles-Murguia, Maricela; Ramalho-Ortigao, Marcelo (2013)

The peritrophic matrix (PM) plays a key role in compartmentalization of the blood meal and as barrier to pathogens in many disease vectors. To establish an infection in sand flies, Leishmania must escape from the endoperitrophic ...
Comparative evaluation of population effect and economic potential of biological suppression tactics versus chemical control for squash bug (Heteroptera: Coreidae) management on pumpkins

Olson, D. L.; Nechols, James R.; Schurle, Bryan W. (1996)

Field releases of the indigenous egg parasitoid Grayon pennsylvanicum (Ashmead) resulted in a 4-fold reduction in squash bug, Anasa tristis (De Geer), densities on 'Jack-O-Lantern' pumpkins in 1991. However, pest populations ...
A comparative study of cannibalism and predation in seven species of flour beetle

Alabi, Taofic; Michaud, J.P.; Amaud, Ludovic; Haubruge, Eric (2008)

1. The present study quantified egg and pupal cannibalism, and interspecific predation on eggs and pupae, by larvae and adults of seven species of flour beetle ( Tribolium spp.) under laboratory conditions: T. anaphe , ...
Comparison of thermal responses, reproductive biologies, and population growth potentials of the squash bug egg parasitoids Ooencyrtus anasae and O. sp. (Hymenoptera: Encyrtidae)

Tracy, J. L; Nechols, James R. (1988)

Laboratory investigations of the gregarious squash bug egg parasitoids Ooencyrtus anasae (Ashmead) and O. sp. were conducted at 20.8, 23.0, and 26.6°C. Females of both species emerged with undeveloped ovaries. Oöcyte ...
Comparisons between the squash bug egg parasitoids Ooencyrtus anasae and O. sp. (Hymenoptera: Encyrtidae): development, survival,and sex ratio in relation to temperature

Tracy, J. L.; Nechols, James R. (1987)

Laboratory investigations of the gregarious squash bug egg parasitoids Ooencyrtus anasae and O. n. sp. near anasae (O. sp.) were conducted at 20.8, 23.0, and 26.6°C. In both species, total developmental periods (egg to ...
Deep sequencing and genome-wide analysis reveals the expansion of MicroRNA genes in the gall midge Mayetiola destructor

Khajuria, Chitvan; Williams, Christie E.; El Bouhssini, Mustapha; Whitworth, R. Jeffery; Richards, Stephen; Stuart, Jeffrey J.; Chen, Ming-Shun (2013)

Background: MicroRNAs (miRNAs) are small non-coding RNAs that play critical roles in regulating post transcriptional gene expression. Gall midges encompass a large group of insects that are of economic importance and also ...
Determination of silicon concentration in some horticultural plants

Hogendorp, Brian K.; Cloyd, Raymond A.; Swiader, John M. (2012)

Although silicon is not an essential element, it is taken up by plants but is rarely quantified. Therefore, this study quantified the silicon concentration in 10 commonly grown horticultural plants including meadow sage ...
Diel activity patterns of the squash bug egg parasitoid Gryon pennsylvanicum (Hymenoptera: Scelionidae)

Vogt, Elizabeth A.; Nechols, James R. (1991)

Mated, 1-d-old female Gryon pennsylvanicum (Ashmead) exhibit a diel pattern of activity and rest. Daily activity (e.g., oviposition, walking, grooming, flying, feeding) is greatest during morning hours (0815-1215 hours ...
Dietary complementation across life stages in the polyphagous lady beetle Coleomegilla maculata

Michaud, J.P.; Jyoti, J.L. (2008)

We investigated the life history consequences of changes in diet between larval and adult life stages in the polyphagous lady beetle Coleomegilla maculata DeGeer (Coleoptera: Coccinellidae). Beetles were reared on three ...
Effect of sugar-based compounds in enhancing the efficacy of insecticides against the western flower thrips

Cloyd, Raymond A.; Gillespie, Joshua D. (2012)

It has been proposed by greenhouse producers that adding sugar to a stomach poison insecticide enhances the efficacy of the insecticide in controlling western flower thrips (Frankliniella occidentalis). As such, a series ...
Effectiveness of sulfuryl fluoride for control of different life stages of stored-product psocids (Psocoptera)

Athanassiou, Christos G.; Phillips, Thomas W.; Aikins, M. Jamie; Hasan, M. Mahbub; Throne, James E. (2012)

With the phase-out and impending ban of methyl bromide, sulfuryl fluoride is among the most promising alternative fumigant insecticides for control of stored-product insect pests. It has been evaluated for control of ...
Effects of squash leaf trichome exudates and honey on adult feeding, survival, and fecundity of the squash bug (Heteroptera: Coreidae) egg parasitoid Gryon pennsylvanicum (Hymenoptera: Scelionidae)

Nechols, James R.; Olson, D. L. (1995)

A laboratory experiment was conducted to determine whether leaf exudates could be used as a source of adult nutrition for the squash bug, Auasa tristis (De Geer), egg parasitoid, Gryon pennsylvanicum (Ashmead), and to ...
